Blender

Blender blends state of the art features into a seamlessly furbished interface that puts you in control of its functionality by full customization. Yes, you have read this right, all UI components and tools can be moved around as you like. And there are quite a few of them to be moved. Starting with character modeling and GLSL support, and ending with rigging, that being the possibility to transform any model into a possible character, the image editor has them all.

Modeling can also be done with hard surfaces. 2D bitmap and 3D procedural brushes add to an impressive list of features. Obviously, non-linear animation and rendering come as basic options with this software.

Stunning visuals and particle physics make for unprecedented game and image creation.
